Abstract

See full text

A motor includes a stator, a rotor, and a magnetic sensor. The stator includes an annular stator core. The stator core surrounds a central axis extending in an axial direction. The rotor is rotatable about the central axis. The rotor includes a first magnet, a second magnet, and a spacer. The first magnet is outward in a radial direction with respect to the stator core. The second magnet extends in one axial direction with respect to the first magnet and the stator core. The spacer is between the first magnet and the second magnet in the axial direction. The magnetic sensor detects a magnetic force of the second magnet. The spacer is made of a non-magnetic material.
